The offset and width will be fine. I don't see the bolt pattern listed (which is 100 x 5 for the Vibe), but the models shown as covered match. The biggest issue is tires: First, 19" rubber costs a ton. Second, with anything close to a stock outside diameter, you will need dead smooth streets or pothole radar to keep from bending them, due to the short sidewall. Also, try checking out the appearance of this or a similar wheel as installed on your Vibe on something like the
